Various packages did and do use constructs like SetLDFLAGS: -L.
or SetLDFLAGS: -L%b/lib/.libs and similar. Sometimes this is really the only way to do it, but often it is dangerous and should instead be handled by a patch. Let me explain: typical, you have to add this because it turns out the package will otherwise link against an already installed version of itself during build time, rather than against the freshly built version. That in turn is because by default, Fink sets LDFLAGS to -L%p/lib. Now most build systems (anything autotool based at least) will *prepend* this to the LDFLAGS. Hence, /sw/lib will be searched before anything else, resulting in the wrong link behaviour. Thus, often the trick listed above is used to get them to link against the "local"/new version of the lib again. However, in many cases (when using libtool at least) this will yield in installed files that have /sw/src/root-FOOBAR/... hard coded in some way! Also this is only a partial fix, since other things (often hard to notice) may go wrong by this. For example, the libxml2 and libxslt package until recently suffered greatly from this whenever they had to be upgraded. Thus, very often it's advisable to use NoSetLDFLAGS: true to prevent -L%p/lib from being prepended. Then, patch the relevant configure/Makefile/whatever files to have the /sw/lib path near the end of LDFLAGS (or wherever is most suitable). This can solve some very annoying bugs, e.g. I am fairly convinced that the big troubles we had (and maybe still have) with qt3 & updating qt3 are caused by this. Packages that use this approach, and which therefore their maintainers might want to recheck include: Masanori Sekino: oaf-0.6.8-1.info mozilla-0.9.9-4.info Alexander Strange: gimp-1.2.3-7.info Andrei Verovski: mysql-3.23.49-2.info Jeffrey Whitaker: gtk+extra-0.99.17-1.info Christoph Pfisterer (i.e unmaintained): giflib-4.1.0-3.info libungif-4.1.0b1-4.info mesa-3.5-1.info Note that these packages do not have to be broken at all! This is just a possibility, it may very well be that they package work 100% correct. Also, these packages put -L%p/lib into SetLDFLAGS, although this is automatically added to LDFLAGS anyway. Authors might want to check up on those, too, and possibly get rid of the additional -L%p/lib: graphics/gimp-perl-1.211-1.info languages/g-wrap-1.1.11-3.info sci/octave-2.1.35-7.info sci/octave-atlas-2.1.35-3.info sci/tela-1.34-3.info Cheers, Max -- ----------------------------------------------- Max Horn Software Developer email: <mailto:[EMAIL PROTECTED]> phone: (+49) 6151-494890 _______________________________________________________________ Have big pipes?
